Mutating the entire genome

...lops. “If we now improve that 10,000-fold, the pool of cells [with translocated chromosomes] may be large enough to create a mouse that develops the cancer,” so the new method makes it easier to breed mice with human cancers, Capecchi says. ‘Jumping Genes’ Help Make More Mutant DNA Wu and Cap...

Human stem cell treatment restores motor function in paralyzed rats

...fting new spinal stem cells, which repopulates the pool of degenerated neurons.” For this study, nine of 16 rats with induced spinal cord ischemia were injected with human spinal stem cells 21 days after paralysis. The other seven were injected with medium that contained no stem cells. The recovery o...

Master regulatory gene of epithelial stem cells identified

...al. Some studies found that p63 maintains a steady pool of the regenerative cells, while other studies argued that p63 has more to do with causing the cells to differentiate into particular types of tissue. The study, which was lead by Frank McKeon, PhD, professor of cell biology at Harvard Medical School...

The quest for an effective HIV vaccine presents new possibilities, challenges

...ng-term HIV infection may close permanently once a pool of latently infected cells is in place, Drs. Johnston and Fauci note. Neutralizing antibodies, which can attach to and eliminate free virus, only appear after HIV levels have declined substantially. Further, the effectiveness of these antibodies is s...

Manipulating nature: Scientists query wildlife birth-control method

... engineering: "Immunocontraception alters the gene pool of the targeted species because those animals who are unresponsive are genetically unusual individuals," he says. "The job of the immunological system is to combat disease-causing organisms. But there is a danger that the selected minority might ...

Researcher to study astronaut bone loss for space biology agency

...er two Fellows were chosen from among a nationwide pool of applicants. "The loss of mechanical forces on bone in the weightlessness of space dramatically weakens bone," says Long. "The ability of humans to conduct prolonged missions to the moon and Mars will require that the structural integrity of the...

Twin studies reveal genetic components leading to cardiac and kidney disease

Since the Homo sapiens populations usually had to pass through several genetic bottlenecks on their way across the globe...

Flavanols in cocoa may offer benefits to the brain

...n are paralleled by an increase in the circulating pool of nitric oxide, a critical molecule in the circulatory system that helps dilate blood vessels and keeps them pliable. Hollenberg fed flavanol-rich cocoa to healthy volunteers who were over age 50 and observed a “striking blood flow response?that e...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

"The vast pool of genetic material in plants can be an important resource from which biotechnology can draw genes for insertion into an array of plants, generating unique genomes not achievable by conventional breeding," Messing said. "We could engineer plants to p...

Who gives stem cells their marching orders?

... attach to the wall of the uterus, to expand their pool of stem cells, and to let individual cells know where they are with respect to their neighbors. However, to carry out these tasks, the Nodal protein must be cleaved by specific enzymes. The enzymes act as a sort of regulatory switch, increasing the s...

Researchers in Montréal and the US create model of key immune-system component
